Hello I have involved in the octave project. Octave uses gnuplot as a graphic backend and data are sent and recieved via pipe.
A report of slowness issue of the plot on octave on windows reported. Please see http://www.nabble.com/Plotting-with-3.2.0-on-Windows-is-SLOOOOOOWWWW-td24703690.html In the reply I have shown the results on octave on cygwin. http://www.nabble.com/Re:-Plotting-with-3.2.0-on-Windows-is-SLOOOOOOWWWW-p24706929.html With Octave on cygwin such slowness issue did not happen. I suppose that this is due to the posix pipe in the cygwin. I have a curiosity how cygwin to realize the posix pipe? The knowledge may help to overcome this issue. Is the win32 pipe fuction like CreatePipe Function used in the cygwin ? http://msdn.microsoft.com/en-us/library/aa365152(VS.85).aspx In the octave for native windows (not cygwin) uses win32 pipe function and implement octave_popen2 () which is like popen2 in the posix. (In the Unix code inculding cygwin used pipe funtion to implement) Thank you in advance for your kind consideration.
